Abstract: 674,684. Battery separators. WILLARD STORAGE BATTERY CO. May 10, 1950 [Sept. 15, 1949], No. 11620/50. Class 53. [Also in Group VIII] A separator comprises a film of synthetic resin containing heterogeneouslyarranged cellulose fibres and is made by impregnating a web of the fibres with a suspension of heatsoftenable resin particles, drying and heating the web to cause the resin to soften and flow. The quantity of added resin is from 50 to 60 per cent of the weight of the dry web. The suspension may consist of particles of styrene, butadiene or polyvinyl chloride and polystyrene and a solvent emulsified in water. Fig. 1 shows an apparatus for making a long length of separator material which is subsequently cut to the required size. A sheeting A of cellulose fibres such as cotton, linen, or wool, is formed on a belt B by plying a number of thin cotton &c. webs 10 from a series of cards C. The plied non-woven sheet A is passed between rollers 11, 12 while the resin latex is distributed over the roller 12 from a reservoir 13. The impregnated sheet is passed through an oven D which is at a sufficient temperature to partially fuse the resin. The sheet is wound on a spool E. Separators cut from the sheet may be plied by a mould press heated by steam which partially fuses the resin and simultaneously forms a pattern of hemispherical bosses on the separator, as shown in Fig. 4.

Title: Improvements in hand address-printing machines
IPC: B41L45/02
Filed: 1955-04-22
Abstract: 778,431. Addressing-machines. ADREMAWERKE GES. April 22, 1955 [April 24, 1954], No. 11631/55. Class 100(2) In a manually-operated addressing- machine, the handle for depressing the printing arm 1, Fig. 1, about a shaft 2 for the printing operation also acts as a member for controlling the print, skip and repeat operation of the machine. The handle is carried on a shaft 5 and can be set to one of three angular positions. "I" for normal printing once from each plate, "O" for skipping a plate, and "OO" for repeat printing from the same plate. Rotation of the handle acts through a lever 6, wire tension member 7, bell-crank 8, bar 11, lever 12, bar 13 and lever 14 to rotate shafts 25, 15. The shaft 15 carries a cam 23 which engages a pawl in the plate transport slide to render the plate feed inoperative in position "OO." The shaft 15 also acts through a lever 16 to reciprocate a resilient bar 17, guided by means of a slot 18 on a stationary pin 19 and carrying an abutment 20 in the form of a rectangular block having an inlay of sound-deadening material. In position "O," the block underlies. an arm 22 on the printing arm 1 and prevents complete depression of the latter, the movement of which is taken up resiliently by the bar 17. The shaft 25 carries a lever 38, Fig. 5, of adjustable length, carrying a roller 39 engaging a lever 40 resting on a link 32 urged upwards by a spring 36. In positions "I" and "OQ," the lever 38 is inclined to the vertical and the link 32 assumes the upper position shown in full lines whereupon the motion of a driving lever 31, Figs. 1 and 5, moved in dependence on the printing arm 1 is transmitted through an extension 34 and the link 32 to a lever 33 pivoted on the machine frame, to which lever 33 pivoted on the machine frame, to which lever 33 is connected by hanging in a hole 41 or 42, a transport rod for feeding a listing strip through one or two lines respectively. In position "I," the roller 39 depresses the link 32, and the extension 34 rides freely in an arcuate slot 35, thus rendering the strip feed inoperative. In another form of strip feed control, Fig. 7. the bar 17 is extended to rest on the link 32, which is held in its upper or lower position according as it underlies the edge surface 45, in position "O," or one of two notches 44, in positions "I" or "OO" of the bar 17.

Title: Carburetor
IPC: F02M1/10
Filed: 1953-04-30
Abstract: 748,457. Carburetters. BENDIX AVIATION CORPORATION. April 30, 1953 [July 3. 1952], No. 12002/53. Class 7(3) A control mechanism for the throttle of a carburetter having a choke valve and a shaft for the choke valve, comprises a fast idle cam adapted to rotate on the shaft of the choke valve and yieldably connected thereto and a throttle lever rigidly secured to the throttle shaft and further includes a control lever rotatably mounted on the throttle shaft adjacent the throttle lever and adapted to engage the cam and a means forming a one way connection between the control lever and throttle lever and adapted to limit closing of the throttle during normal and fast idle operation. A fast idle cam 24 carrying a counterweight 34 is loosely mounted on a shaft 18 of a preferably off-set choke valve (not shown), and is operated by the choke valve by means of an arm 38 fixed to the shaft 18 and a spring 40 one end of which engages the arm 38 and the other end of which co-operates with a lug 44 on the fast idle cam. The cam limits the idling position of the throttle valve (not shown), by the engagement of a screw 61 carried by an arm 50 secured to the throttle valve shaft 16 with a. lug 62 carried by lever 56 which is rotatably mounted on the shaft 16. A finger 59 at the upper end of the lever 56 engaging the cam 24. The spring 40 permits the choke valve to be moved while the finger 59 is preventing rotation of the cam 24. The choke valve is controlled by an automatic choke unit (not shown), consisting of a vacuum actuated piston and a thermosensitive coil. Hot air is supplied to the unit from a point adjacent the exhaust manifold. When the throttle valve is moved to wide open position an arm 70 engages an ear 72 thus moving the lever 56 to the right and causing a finger 74 to engage the arm 38 (when the latter is in the position shown), and thus move the choke valve to partially open position. At the same time an ear 84 engages the stem 86 of a kickdown switch 26 for initiating a change in transmission speed ratio drive. A dashpot 28 retards the final closing movement of the throttle valve but an electrically controlled valve renders the dashhpot, ineffective under certain conditions. The acceleration pump is operated by the throttle valve by means of lever 88 and links 90, 92.
Patent GB-732867-A (GB)
Title: Improvements in or relating to circuit arrangements for controlling the gradation ofpicture signals
IPC: H04N5/20
Filed: 1953-05-04
Abstract: 732,867. Electric analogue calculating machines. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 4, 1953 [May 7, 1952], No. 12307/53. Class 37. [Also in Group XL (c)] In a television gamma control circuit for example for producing an output voltage proportional to the input voltage raised to the power 0.3 or 0.4 positive-going picture signals are amplified in valve 8 and applied to valves 1, 2 and 3 having a common output load and having their grid circuits arranged to stabilize the black level at zero voltage. The range of input voltage applied to valve 1 is equal to the grid base of the valve while that applied to valve 2 is greater and valve 3 still greater than their respective grid bases so that the circuit as a whole has a non-linear characteristic. The non-linearity may be varied without varying the peak output voltage from the circuit by adjusting the amplitude of the signal voltage applied to valves 2 and 3. The anodes of valves 2 and 3 may alternatively be connected through resistors to the common load or to tapping points thereon (Figs. 3 and 4, not shown).

Title: Improvements in or relating to electro-magnetic relays or like devices
IPC: H01H51/04
Filed: 1921-04-29
Abstract: 162,673. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Erickson, J.). May 6,1920, [Convention date]. Electromagnetic and magnetic actuation.-Relates to relays, for use in automatic telephone systems &c., in which the relay is provided with a main armature and an auxiliary member or armature, so arranged as to enable the main armature to take up one of two stable attracted positions, corresponding to comparatively strong and week energizing currents, whereby one or other of two switching operations is performed by the armature. Figs. 1 and 3 show one form of relay comprising a core 2 with a pair of windings, supported by a heel-piece 3, which also carries the contact springs. The main armature 4, which is pivoted at 5, is perforated over the centre of the core to receive a rivet-shaped auxiliary armature 13 of soft iron, having a brass sheath 14. The enlarged head 12 of the auxiliary armature 13 is arranged to move within a housing 8 secured by screws 9, 10 to the main armature. When the core is feebly energized, the main portion of the flux passes through the auxiliary armature, which is attracted to the core, thereby closing a secondary magnetic circuit, which renders the attracted position a stable one, and as the auxiliary armature carries the main armature, the centre contact spring is forced out of engagement with its resting contact. The secondary magnetic circuit through the armature 13 includes the air gap formed by the brass sheath 14, and if the energizing current is steadily increased a critical point is reached at which the leakage from this magnetic circuit between the main armature and the core is sufficient to attract the main armature, thereby completing the second circuit, during which motion the auxiliary armature 13 moves upwards within the casing 8. In order to permit of adjustment of the air gap in the secondary magnetic circuit, the modified form of relay shown in Fig. 5 is employed. The main armature 34 only partially covers the end of the core, an L-shaped auxiliary armature 40 being secured by non-magnetic rivets 45, 46 to a non-magnetic member 42 pivoted coaxially with the main armature 34, the lower end of rivets 45, 46 resting on the main armature 34. An iron screw 41 passes through the auxiliary armature 40, an adjustable gap separating its lower end from the main armature 34, and spring washers 44, 45 retaining the screw 41 in its adjusted position. As the gap Between the auxiliary armature 40 and the core is smaller than that between the main armature 34 and the core, the relay operates in the manner above-described.

Abstract: 198,536. Regan, J. B. May 2, 1922. Track apparatus for stopping trains.-Traincarried apparatus controlling the brake valve and responsive to ' clear,' ' caution ' and ' danger ' conditions of the track comprises a generator G supplying alternating current to the primary coils J, J<1> of a transformer, the secondary of which D<1> energizes one coil of a two coil relay A which controls the stick-circuit to a relay B. At each signalling ,point, a device E on the track diverts the magnetic flux from the coils D<1> and the ralay A is de-energized. The device E may comprise a plate or bar of iron fixed on the track. The train carries at each side or on its centre line and longitudinally displaced, an energized coil 28 and a pick-up coil 16, which pass over the coils T", T<2> on the track. The circuits of the track coils include contacts controlled by home and distant relays H, D so that the coils may be connected in series normally or reversed or be disconnected under ' clear,' ' caution ' and ' danger ' conditions respectively. Thus, the coil 16 supplies energy to the coil 13 of the relay C in phase with or in opposition to that supplied to the coil 13<1> and the relay B is correspondingly energized by way of its pick-up circuit through the armatures 17, 18 and remains energized through the stick-circuit over its own armatures 22, 31 and the contacts of the relay A. At a clear signal, the contact 40 of relay B closes the circuit of the brake-valve magnet M enabling the train to proceed at any speed. At a caution signal, the contact 40 is put in series with a speedometer contact S and the circuit to the magnet M is closed only at speeds below a predetermined limit.
